other two? [laughter] there be. there be. they're called engineers in science types, in physics types. in fact, they're us types, aren't they? what's the wavelength, gang? let's go. watch this, one, one, two, two, three, three, four, four, five, five, now it's 3/14. okay. so wavelength equals 3/14 of a what? - kilometer. - kilometer. okay? that's like 3,000 meters divided by 14. why did you pick a four, man? i mean--how many times does 14 go into 3,000? does anyone have a calculator? 214.28571. 214 meters long. is that surprising to you? that's like two football fields and then some. so the wavelength of your favorite radio station is more than two football fields long. radio waves are long or short compared to light waves, gang? we'll do the same thing for light waves later on and find out it's a smidge, smidge, smidge, smidge, smidge. zero's go the other way. yey. anyway, that's how you find the wavelength of something. i can show you the slinky here. can someone grab the end of this for an "a" in the course. [laughter] right over here. now, i'm gonna take this wave and i'm go

university professor? >> i think in the sciences particular and the energy secretary, it is increasingly common. steven chu, the outgoing energy secretary who is also an academic, had close ties also to bp. bp had given a bunch of money to steven chu's slap at the university of california berkeley and he picked an executive to be one of his undersecretaries. steven chu was later involved in the government's response to the gulf oil spill. i think this is certainly, if you're going to be picking an academic who is involved in energy, in particular, fossil fuel research. >> i want to turn to comments of the executive director the natural resources defense council. earlier this month peter posted a to do list for the new energy secretary. and it he wrote -- nrdc is supporting the nomination m theoniz. >> i think the best way to interpret his nomination is he fits in with what obama has called his all of the above policy, which is to embrace things like fracking, continued use of oil, nuclear energy but also develop wind and solar i think that is where ernest moniz is on energy.

. sequestration is simply a cutback in government spending. it does not take rocket science to understand that if the government of the largest single buyer of goods and services cuts back on the goods and services it buys, that means companies across america will sell less and they will have less need of workers and it will lay off workers. so this is in fact that worsens and employment is already severe. if you put that together with the tax increase on january 1 -- let me say a word about that. we heard a lot of public debate about taxing rich people and not taxing rich people, republicans and democrats, but the tax on the wealthy is small compared to the tax on the middle and lower incomes that went up january 1. when we raise the payroll tax from 4.2% to 6%, we raised over $125 billion, much more that was raised by taxing the rich, and we savaged the middle and lower income groups in america, those that in the presidential election both candidates had sworn to save and support. we attack them, thereby limiting their capacity to buy goods and services. you put together the taxing of t

. ain't that neat, huh? the wonders of science, yay. all right? we call that resonance, gang. resonance. now, hc. how come this resonate? we can understand resonance if we think small. this is something you can really understand. watch. i'm gonna strike this. this thing is gonna-- flap back and forth, yeah. flap back and forth. isn't it like that ping pong ball, hitting the balls, right? those things like-- back and forth to you. and also we have--over here. yep. do you believe that little pitter-patters of molecules could bend hard steel? yep. how many say, "oh, no, that could never happen"? come on. i can set this thing vibrating those little molecules, yeah? yep. okay, here we go. i hit this. boom. now, let's look at-- let's slow it down. high pressure hits this prong, yeah? bends it, right? okay. now, what follows the high pressure? lower pressure. so what it does? it swings back to where it started, over shoots over here and right to here. and what happens right then? right then, right then, right then. bam. you see why the timing is important? at that particular instance, the next
